Lyon County Building and Safety Division
Lyon County, Nevada, has a Building Department that oversees building permits, including those for plumbing, within its jurisdiction. This department is responsible for enforcing building codes and ordinances to ensure the health, safety, and general welfare of the community. For properties located in unincorporated areas of Lyon County, the county's Building Department is the relevant authority for permit requirements.
Generally, all new construction, repairs, or remodeling of buildings and structures in unincorporated Lyon County require permits. Exceptions exist for certain fences and detached accessory structures under 200 square feet that do not include electrical or plumbing.
All structures must comply with the adopted building codes, which include the 2024 Uniform Plumbing Code (UPC) as of January 1, 2026. A residence must be the first building permitted, constructed, and approved for occupancy.
Permit applications will not be accepted without addressing provisions for water and sewer services. This typically requires documentation such as "will serve" letters from utility districts, well driller's contracts, or septic system applications with percolation test data.
Lyon County also allows for "Owner-Builder" permits under specific circumstances, requiring appropriate affidavits and owner occupancy for at least one year after final approval.
Rules for Properties in Unincorporated Areas
For properties in unincorporated areas of Lyon County, the County Building Department handles all permit requirements. This includes obtaining permits for new construction, additions, alterations, and repairs.
Development permits, which include building permits, are required for various activities such as filling, excavating, grading, paving, and constructing or enlarging structures. Specific permits may also be needed for site improvements, grading, and encroachments onto public roads.
Plumbing work, like other construction activities, falls under the purview of the Lyon County Building Department. Permits are required for plumbing installations and significant repairs.
The county has adopted specific building codes, including the 2024 Uniform Plumbing Code, which must be adhered to for all permitted work. Plan submittals must comply with these adopted codes.

Plumbing Code Adoption in Nevada
In Nevada, plumbing standards are primarily governed by the adoption of the Uniform Plumbing Code (UPC), published by the International Association of Plumbing and Mechanical Officials (IAPMO). The State of Nevada Public Works Division adopts the most current edition of the UPC for state-owned facilities, and local jurisdictions (cities and counties) are responsible for adopting and enforcing plumbing codes within their respective boundaries, often incorporating local amendments to the UPC.
Primary State Agencies and Regulatory Framework
The regulatory framework for plumbing in Nevada involves several key entities:
- State Public Works Division (SPWD): The SPWD is responsible for adopting and enforcing building codes, including the UPC, for all projects involving state-owned facilities.
- State Board of Health: Under the Nevada Administrative Code (NAC), the State Board of Health is authorized to adopt the Uniform Plumbing Code by reference for sanitation and public health purposes.
- Local Jurisdictions: Cities and counties in Nevada have the authority to adopt their own building and plumbing codes. Many jurisdictions, particularly in Southern Nevada, work through regional bodies like the Southern Nevada Building Officials (SNBO) to adopt the UPC along with regional amendments to ensure consistency across the area.
- Nevada Revised Statutes (NRS): State law, specifically within chapters such as NRS 278 and NRS 444, provides the legal authority for local governments to adopt and enforce plumbing regulations and establishes minimum standards for plumbing fixtures (e.g., water consumption limits).
